Procurement API (procurement)

The procurement module serves suppliers, substitution groups, critical materials, purchase requests, purchase RFQs with a supplier portal, purchase orders with goods receipt, purchase contracts, purchasing info records, and MRP. All 155 endpoints sit under /api/v1/procurement. For business meaning see the Procurement module page. Because the full table exceeds the page length limit, each sub-module has its own page.

Group facts¶

Endpoint summary¶

One row per sub-module folder. The router prefix is added to the base path. The page column links the endpoint table.

Error codes¶

The table lists the error codes that code under src/cluster_erp/modules/procurement/ raises, found by a syntax-tree scan for AppError(...), the factories in src/cluster_erp/core/errors.py (not_found, conflict, protected, permission_denied, privilege_escalation, check_version), and HTTPException(...). A status of 400 is the AppError default (src/cluster_erp/core/errors.py:23). Guard errors (401, 403), the entitlement codes, and validation errors (422) apply to every route and are listed on Errors.

Events emitted¶

The table lists the contract classes that code under src/cluster_erp/modules/procurement/ passes directly to EventBus.emit, found by a syntax-tree scan. Events built in a variable first are not counted. The contracts are described in Contracts reference.
